* (x/bank) [\#10771](https://github.com/cosmos/cosmos-sdk/pull/10771) Add `bank.BankKeeper.WithMintCoinsRestriction` function to restrict use of bank `MintCoins` usage. This function is not on the bank `Keeper` interface, so it's not API-breaking, but only additive on the keeper implementation.
* (x/auth) [\#10880](https://github.com/cosmos/cosmos-sdk/pull/10880) Added a new query to the tx query service that returns a block with transactions fully decoded.
* (grpc) [\#10985](https://github.com/cosmos/cosmos-sdk/pull/10992) The `/cosmos/tx/v1beta1/txs/{hash}` endpoint returns a 404 when a tx does not exist.

* [\#10393](https://github.com/cosmos/cosmos-sdk/pull/10393) Add `HasSupply` method to bank keeper to ensure that input denom actually exists on chain.
* (std/codec) [/#10595](https://github.com/cosmos/cosmos-sdk/pull/10595) Add evidence to std/codec to be able to decode evidence in client interactions.
* [\#9829](https://github.com/cosmos/cosmos-sdk/pull/9829) Fixed Coin denom sorting not being checked during `Balance.Validate` check. Refactored the Validation logic to use `Coins.Validate` for `Balance.Coins`

* [\10608](https://github.com/cosmos/cosmos-sdk/pull/10608) Change the order of module migration by pushing x/auth to the end. Auth module depends on other modules and should be run last. We have updated the documentation to provide more details how to change module migration order. This is technically a breaking change, but only impacts updates between the upgrades with version change, hence migrating from the previous patch release doesn't cause new migration and doesn't break the state.
* [\#10045](https://github.com/cosmos/cosmos-sdk/pull/10045) Revert [#8549](https://github.com/cosmos/cosmos-sdk/pull/8549). Do not route grpc queries through Tendermint.

* (x/feegrant) [\#10049](https://github.com/cosmos/cosmos-sdk/issues/10049) Fixed the error message when `period` or `period-limit` flag is not set on a feegrant grant transaction.
* [\#9879](https://github.com/cosmos/cosmos-sdk/pull/9879) Modify ABCI Queries to use `abci.QueryRequest` Height field if it is non-zero, otherwise continue using context height.
* [\#9860](https://github.com/cosmos/cosmos-sdk/pull/9860) Emit transaction fee in ante handler fee decorator. The event type is `tx` and the attribute is `fee`.
* (x/upgrade) [\#9906](https://github.com/cosmos/cosmos-sdk/pull/9906) Deprecate `UpgradeConsensusState` gRPC query since this functionality is only used for IBC, which now has its own [IBC replacement](https://github.com/cosmos/ibc-go/blob/2c880a22e9f9cc75f62b527ca94aa75ce1106001/proto/ibc/core/client/v1/query.proto#L54)

* (rosetta) [\#8729](https://github.com/cosmos/cosmos-sdk/pull/8729) Data API fully supports balance tracking. Construction API can now construct any message supported by the application.
* [\#9750](https://github.com/cosmos/cosmos-sdk/pull/9750) Emit events for tx signature and sequence, so clients can now query txs by signature (`tx.signature='<base64_sig>'`) or by address and sequence combo (`tx.acc_seq='<addr>/<seq>'`).
* [\#8363](https://github.com/cosmos/cosmos-sdk/pull/8363) Addresses no longer have a fixed 20-byte length. From the SDK modules' point of view, any 1-255 bytes-long byte array is a valid address.
* [\#8849](https://github.com/cosmos/cosmos-sdk/pull/8849) Upgrade module no longer supports time based upgrades.
* [\#7477](https://github.com/cosmos/cosmos-sdk/pull/7477) Changed Bech32 Public Key serialization in the client facing functionality (CLI, MsgServer, QueryServer):
* updated the keyring display structure (it uses protobuf JSON serialization) - the output is more verbose.
* Renamed `MarshalAny` and `UnmarshalAny` to `MarshalInterface` and `UnmarshalInterface` respectively. These functions must take an interface as parameter (not a concrete type nor `Any` object). Underneath they use `Any` wrapping for correct protobuf serialization.
* CLI: removed `--text` flag from `show-node-id` command; the text format for public keys is not used any more - instead we use ProtoJSON.
* [\#9859](https://github.com/cosmos/cosmos-sdk/pull/9859) The `default` pruning strategy now keeps the last 362880 blocks instead of 100. 362880 equates to roughly enough blocks to cover the entire unbonding period assuming a 21 day unbonding period and 5s block time.

* (x/staking) [\#8473](https://github.com/cosmos/cosmos-sdk/pull/8473) On genesis init, if non bonded pool and bonded pool balance, coming from the bank module, does not match what is saved in the staking state, the initialization will panic.
* (x/gov) [\#8473](https://github.com/cosmos/cosmos-sdk/pull/8473) On genesis init, if the gov module account balance, coming from bank module state, does not match the one in gov module state, the initialization will panic.
* (x/distribution) [\#8473](https://github.com/cosmos/cosmos-sdk/pull/8473) On genesis init, if the distribution module account balance, coming from bank module state, does not match the one in distribution module state, the initialization will panic.
* (x/staking) [\#8505](https://github.com/cosmos/cosmos-sdk/pull/8505) `sdk.PowerReduction` has been renamed to `sdk.DefaultPowerReduction`, and most staking functions relying on power reduction take a new function argument, instead of relying on that global variable.
* [\#8629](https://github.com/cosmos/cosmos-sdk/pull/8629) Deprecated `SetFullFundraiserPath` from `Config` in favor of `SetPurpose` and `SetCoinType`.
* (x/upgrade) [\#8673](https://github.com/cosmos/cosmos-sdk/pull/8673) Remove IBC logic from x/upgrade. Deprecates IBC fields in an Upgrade Plan, an error will be thrown if they are set. IBC upgrade logic moved to 02-client and an IBC UpgradeProposal is added.

* (x/upgrade) [\#8743](https://github.com/cosmos/cosmos-sdk/pull/8743) `UpgradeHandler` includes a new argument `VersionMap` which helps facilitate in-place migrations.
* (x/upgrade) [\7487](https://github.com/cosmos/cosmos-sdk/pull/8897) Upgrade `Keeper` takes new argument `ProtocolVersionSetter` which implements setting a protocol version on baseapp.
* (baseapp) [\7487](https://github.com/cosmos/cosmos-sdk/pull/8897) BaseApp's fields appVersion and version were swapped to match Tendermint's fields.
* [\#8682](https://github.com/cosmos/cosmos-sdk/pull/8682) `ante.NewAnteHandler` updated to receive all positional params as `ante.HandlerOptions` struct. If required fields aren't set, throws error accordingly.
*`ValidatorI` interface update: `GetConsPubKey` renamed to `TmConsPubKey` (this is to clarify the return type: consensus public key must be a tendermint key); `TmConsPubKey`, `GetConsAddr` methods return error.
*`Validator` updated according to the `ValidatorI` changes described above.
*`ToTmValidator` function: added `error` to return values.
*`Validator.ConsensusPubkey` type changed from `string` to `codectypes.Any`.
*`MsgCreateValidator.Pubkey` type changed from `string` to `codectypes.Any`.

* [\#9139](https://github.com/cosmos/cosmos-sdk/pull/9139) `ServiceMsg` TypeURLs (e.g. `/cosmos.bank.v1beta1.Msg/Send`) have been removed, as they don't comply to the Probobuf `Any` spec. Please use `Msg` type TypeURLs (e.g. `/cosmos.bank.v1beta1.MsgSend`). This has multiple consequences:
*`sdk.Msg` now only contains `ValidateBasic` and `GetSigners` methods. The remaining methods `GetSignBytes`, `Route` and `Type` are moved to `legacytx.LegacyMsg`.
* The `RegisterCustomTypeURL` function and the `cosmos.base.v1beta1.ServiceMsg` interface have been removed from the interface registry.
* (x/bank) [\#9271](https://github.com/cosmos/cosmos-sdk/pull/9271) SendEnabledCoin(s) renamed to IsSendEnabledCoin(s) to better reflect its functionality.
* (x/bank) [\#9550](https://github.com/cosmos/cosmos-sdk/pull/9550) `server.InterceptConfigsPreRunHandler` now takes 2 additional arguments: customAppConfigTemplate and customAppConfig. If you don't need to customize these, simply put `""` and `nil`.
* [\#8245](https://github.com/cosmos/cosmos-sdk/pull/8245) Removed `simapp.MakeCodecs` and use `simapp.MakeTestEncodingConfig` instead.
* (x/capability) [\#9836](https://github.com/cosmos/cosmos-sdk/pull/9836) Removed `InitializeAndSeal(ctx sdk.Context)` and replaced with `Seal()`.

* (x/{bank,distrib,gov,slashing,staking}) [\#8363](https://github.com/cosmos/cosmos-sdk/issues/8363) Store keys have been modified to allow for variable-length addresses.
* (x/gov) [\#7733](https://github.com/cosmos/cosmos-sdk/pull/7733) ADR 037 Implementation: Governance Split Votes, use `MsgWeightedVote` to send a split vote. Sending a regular `MsgVote` will convert the underlying vote option into a weighted vote with weight 1.
* (x/bank) [\#8656](https://github.com/cosmos/cosmos-sdk/pull/8656) balance and supply are now correctly tracked via `coin_spent`, `coin_received`, `coinbase` and `burn` events.
* [\#8880](https://github.com/cosmos/cosmos-sdk/pull/8880) The CLI `simd migrate v0.40 ...` command has been renamed to `simd migrate v0.42`.
* [\#8628](https://github.com/cosmos/cosmos-sdk/issues/8628) Commands no longer print outputs using `stderr` by default
* [\#9134](https://github.com/cosmos/cosmos-sdk/pull/9134) Renamed the CLI flag `--memo` to `--note`.

* [\#9401](https://github.com/cosmos/cosmos-sdk/pull/9401) Fixes incorrect export of IBC identifier sequences. Previously, the next identifier sequence for clients/connections/channels was not set during genesis export. This resulted in the next identifiers being generated on the new chain to reuse old identifiers (the sequences began again from 0).
* [\#9408](https://github.com/cosmos/cosmos-sdk/pull/9408) Update simapp to use correct default broadcast mode.
* [\#9513](https://github.com/cosmos/cosmos-sdk/pull/9513) Fixes testnet CLI command. Testnet now updates the supply in genesis. Previously, when using add-genesis-account and testnet together, inconsistent genesis files would be produced, as only add-genesis-account was updating the supply.
* (x/gov) [\#8813](https://github.com/cosmos/cosmos-sdk/pull/8813) fix `GET /cosmos/gov/v1beta1/proposals/{proposal_id}/deposits` to include initial deposit
### Features
* [\#9383](https://github.com/cosmos/cosmos-sdk/pull/9383) New CLI command `query ibc-transfer escrow-address <port> <channel id>` to get the escrow address for a channel; can be used to then query balance of escrowed tokens

* [\#9026](https://github.com/cosmos/cosmos-sdk/pull/9026) By default, the `tx sign` and `tx sign-batch` CLI commands use SIGN_MODE_DIRECT to sign transactions for local pubkeys. For multisigs and ledger keys, the default LEGACY_AMINO_JSON is used.
### Bug Fixes
* (gRPC) [\#9015](https://github.com/cosmos/cosmos-sdk/pull/9015) Fix invalid status code when accessing gRPC endpoints.
* [\#9026](https://github.com/cosmos/cosmos-sdk/pull/9026) Fixed the bug that caused the `gentx` command to fail for Ledger keys.

**IMPORTANT**: This release contains an important security fix for all non Cosmos Hub chains running Stargate version of the Cosmos SDK (>0.40). Non-hub chains should not be using any version of the SDK in the v0.40.x or v0.41.x release series. See [#8461](https://github.com/cosmos/cosmos-sdk/pull/8461) for more details.
### Improvements
* (x/ibc) [\#8624](https://github.com/cosmos/cosmos-sdk/pull/8624) Emit full header in IBC UpdateClient message.
* (x/crisis) [\#8621](https://github.com/cosmos/cosmos-sdk/issues/8621) crisis invariants names now print to loggers.
**IMPORTANT**: Due to a bug in the v0.41.x series with how evidence handles validator consensus addresses #8461, SDK based chains that are not using the default bech32 prefix (cosmos, aka all chains except for t
he Cosmos Hub) should not use this release or any release in the v0.41.x series. Please see #8668 for tracking & timeline for the v0.42.0 release, which will include a fix for this issue.
* (client/keys) [\#8639] (https://github.com/cosmos/cosmos-sdk/pull/8639) Fix keys migrate for mulitisig, offline, and ledger keys. The migrate command now takes a positional old_home_dir argument.

### API Breaking Changes
* (baseapp) [\#5837](https://github.com/cosmos/cosmos-sdk/issues/5837) Transaction simulation now returns a `SimulationResponse` which contains the `GasInfo` and `Result` from the execution.
where the IAVL no longer keeps states in-memory in which it flushes periodically. IAVL now commits and
flushes every state to disk as it did pre-v0.13.0. The SDK's multi-store will track and ensure the proper
heights are pruned. The operator can set the pruning options via a `pruning` config via the CLI or
through `app.toml`. The `pruning` flag exposes `default|everything|nothing|custom` as options --
see docs for further details. If the operator chooses `custom`, they may provide granular pruning
options `pruning-keep-recent`, `pruning-keep-every`, and `pruning-interval`. The former two options
dictate how many recent versions are kept on disk and the offset of what versions are kept after that
respectively, and the latter defines the height interval in which versions are deleted in a batch.
**Note, there are some client-facing API breaking changes with regard to IAVL, stores, and pruning settings.**
